C:
D:
Correct Answer
A
Explanation
When a red rose flower is observed in blue light, the observer will likely perceive the rose as appearing dark or blackish. This is because red roses primarily reflect and absorb certain wavelengths of light. In this case, blue light contains wavelengths that are not conducive to making the red pigments in the rose appear red to our eyes. Instead, the blue light is absorbed or scattered by the rose's pigments, resulting in a darker or blackish appearance. The specific color and intensity of this dark appearance may vary depending on the particular characteristics of the rose and the lighting conditions.
